Sitting en banc, the U.S. Court of Appeals for the Eleventh Circuit on June 30, 2008, decided Greenberg v. National Geographic Society, finding that the CD-ROM set, "The Complete National Geographic" (CNG), was a privileged revision of a collective work under 17 U.S.C. § 201(c) and not a "new collective work" in violation of Mr. Greenberg's copyrights. This case is in line with the Second Circuit's decision in Faulkner v. National Geographic Enters., further clarified the U.S. Supreme Court's ruling in New York Times Co. v. Tasini, and importantly, upheld the "long embraced doctrine of media neutrality" that the "transfer of a work between media does not alter the character of that work for copyright purposes."
